The next chapter of our fruitful collaboration with the amazing Katy Thakkar has been accepted for publication in the Journal of Neuroscience. Katy's talented student Beier Yao took the lead on this one. What this is about? People with schizophrenia sometimes experience abnormalities in a sense of agency, which may stem from abnormal sensory predictions about their own … Continue reading New J Neuro paper with Katy Thakkar: Structural thalamo-frontal hypoconnectivity is related to oculomotor corollary discharge dysfunction in schizophrenia
Quite some time ago, our paper on perceptual learning during saccade preparation has been accepted for publication in Vision Research. This project started with an idea in 2010, innocently pitched at one of the legendary lunch lab meetings at Patrick Cavanagh's house in Paris. He had just asked me what I'd like to work on … Continue reading Now out: Perceptual learning while preparing saccades
We are happy to announce the publication of a new paper in the Journal of Neuroscience. Effective action in the presence of moving stimuli requires a prediction of their motion trajectory. To investigate the link between motion extrapolation for oculomotor programming and the perception of target position, we used the flash-grab effect to induce illusory … Continue reading New paper on the relation between motion extrapolation for eye movements and perceived position shifts
We are happy to announce that our paper on saccadic selection of visuospatial working memory contents has been published in Consciousness and Cognition. Eye movements help to prioritize information processing in cluttered visual scenes. Specifically, stimuli presented at the future saccade goal are preferentially encoded and maintained in visual short-term memory. In this paper, we … Continue reading New paper on saccadic selection of visuospatial working memory contents
About three years ago, we have started working on perception during saccadic eye movements — that is, when the eyes are in mid-flight from one point in the scene to the next. Using a quite unique high-speed projection setup that allows us to rapidly (yet smoothly) move stimuli on the screen, we keep finding new … Continue reading In the press: All is not lost
We are excited to announce that our new paper on local changes in orientation tuning before saccades has just appeared in the Journal of Vision. Here is the link. Clara and Sven did worked together extremely well to get this project from conception to publication in less than two years! In this study, we combined … Continue reading New paper on dynamic changes orientation tuning before saccades.
Betty's paper on the continuity of feature-based attention across saccadic eye movements has just been accepted for publication in the Journal of Vision. Congratulations, Betty! A pdf of the preprint is available here. And here is the abstract: Saccadic eye movements do not disrupt the deployment of feature-based attention The tight link of saccades to covert spatial … Continue reading In press: New paper on feature-based attention and saccadic eye movements.
Together with Katy Thakkar (Michigan State University) and Vaibhav Diwadkar (Wayne State University), we just wrote an opinion piece on the role of corollary discharge in psychosis, and how prediction in the oculomotor system may help us understand the complex polygenic disorder schizophrenia. The review is going to be published in one of the next issues of … Continue reading Opinion article on Oculomotor prediction in psychosis in press in TiCS
We were happy to see that Steve Lewandowsky highlighted Betty's recent paper on feature-based attention and visual short-term memory at psychonomic.org! Here is a link to the blog.
Congratulations to Alex White, whose postdoc project just appeared in the Journal of Neurophysiology! The key finding of this paper is that the pattern of miniature eye movements immediately following the appearance of a stimulus—the reflexive inhibition of so-called microsaccades—reveals whether the observer has seen that stimulus or not. To some extent, this subjective perception … Continue reading New paper: Oculomotor inhibition covaries with conscious detection
